💡 How does a keyway improve clutch bearing performance?
The keyway keeps the bearing fixed on the shaft, preventing slippage under load and allowing consistent torque transfer. It’s a must for systems that operate under frequent cycling or directional pressure.
A clean, compact solution for one-way torque control in powered drive applications.
